A lot of other glamour only head piece items allow you to dye them, but for whatever reason none of the horn head pieces allow it.
For example:
- Tamamo Headband
- Bunny(+Chief) Crown
- Coeurl Mask
- Swine/Toad/Rabbit/Werewolf Head
- Reindeer Antler Headband
The dyeable horns would allow for a lot more unique looking variations, and yet not a single one of them are dyeable compared to the above items which "function" relatively the same.
- Ultima Horns
- Succubus Horns
- Arch Demon Horns
- Archaeodemon Horns
- Catoblepas Horns
There are only FIVE items so I cannot imagine it would be that much developmental work since they already exist.
I'm sure a lot of people would actually be looking forward to this if it was revealed to be happening considering how much people love glamours.
